What is the definition of the particular Roman Church?
It must be observed moreover, that the Roman Church cannot err in this unfolded way, still can be understood in two ways. In one way, that it cannot err, while the Apostolic See persists at Rome: however it will be otherwise, if the See is transferred. In another way, that it cannot err simply, or fall off, since the Apostolic see cannot at any time be transferred from Rome to another [place].
